APPARATUS FOR INFLATING THE TIRES 0F VEHICLE-WHEELS.

Specification of Letters Patent.

Patented Nov. 14, 1911.

Application filed June 29, 1910. Serial No. 569,543.

To all whom it may concern:

Be it known that I, FELIX KASSNER, a subject of the King of Prussia, German Emperor, and resident of Frauenwaldau, Germany, have invented certain new and useful Improvements in Apparatus for Infiating the Tires of Vehicle-Wheels, of which the following is a specification.

This invention relates to an improved ape paratus for the instantaneous production of gases under high pressure adapted to fill hollow bodies, for example for inflating the air chambers of pneumatic tires for motorcars, etc.

The improved apparatus consists of a hermetically closed transportable vessel in which a substance is ignited which generates gases of high pressure when it is burned. Owing to the sudden ignition of the substance the oxygen of the air contained in the vessel is completely combusted; the gases produced therefore contain merely azote which does not corrode the india-rubber as much as the oxygen. This improved apparatus is therefore particularly useful for inflating air-tires.

The substances used for the production of the pressure are preferably substances which ignite comparatively slowly such as powder, celluloid and the like, but which increase the proportion of azote in the air. The ignition can be produced either electrically or mechanically.

In the accompanying drawings the apparatus is shown.

Figure 1 represents the apparatus in longitudinal section; Fig. 2 is a side elevation of the same; Fig. 3 is a section on line AB of Fig. 1.

The vessel a is made of very solid material. The cover 6 is fixed on the vessel aby means of the hinge 0 and maintained in closed position by the fixing screw (Z which can be replaced by a suitable lever.

To insure an air tight joint between the cover I) and the vessel a a copper ring 6 is mounted in a circular groove of the end of the vessel and the cover I) is provided with a circular rib f destined to bear upon said copper ring when the cover is being closed.

The substance to be burned in the vessel 0 '1s made 1n rods Wl'llCll can be easlly maintained in the vessel a by means of shoulders g, 9 provided in said vessel.

The priming can be effected electrically or mechanically. In the apparatus shown in the drawings percussion priming is employed. The primer h is mounted in a sup port fixed to the inner side of the lid 5. The striking-pin 2' is located in a stuffing box is mounted in a suitable boring ofthe lid 5. The substance to be ignited is placed in the vessel 0; so that it is in easy reach of the thinflame produced when the primer is struck by the pin 2'.

At the bottom end of the vessel a an outlet channel Z is provided which is closed by a valve m. Said valve carries the tubular joint for the reception of the flexible tube 47, destined to conduct the compressed air to the air-tire. A pressure-gage 0 is connected with said tubular joint, being destined to indicate the pressure which exists in the airtire.

I claim An improved apparatus for inflating the tires of vehicle wheels with gas under high pressure comprising in combination an easily transportable vessel open at one end, a lid hinged at the open end of the vessel, means for securely fastening said lid, an igniting device mounted in said lid so that it can be operated from outside the vessel, a gas valve mounted at the closed end of the vessel, ribs in said cylinder, for supporting an explosive compound in proper position with regards to the igniting device, substantially as described and shown and for the purpose set forth.

In witness whereof I have hereunto set my hand in the presence of two witnesses.

FELIX KASSNER.
